Aunov Tech manufactures the Capillary Tube Needle Tube 304 Stainless Steel Malaysia Bright Surface in stainless steel on a single production floor. Once installed, the deep drawn tube carries fluid or motion through a closed drawn wall. The same floor forms, machines and inspects the part, so repeat orders stay aligned with the approved sample with no third party in the loop.
Product overview
What matters most on this stainless steel tube is, the forming route, the tolerance band and the sealing faces, each measured at first article and gauged on production batches.
Toolroom, presses and machining centres used on this stainless steel tube operate on the same site, so the route from print to sample stays short, and every step is logged against the part number.
How it is manufactured
Production of this stainless steel tube is locked to one route: Coil is blanked and drawn through progressive and single-stage dies; the finishing operations hold the concentricity the drawing calls for.
The part tooling and setup record is stored against the part number, so nothing depends on someone remembering. That record is what every part reorder is built on, so nothing changes silently between shipments.
Materials and finishing
The standard stock list carries SPCC / DC01 carbon steel, 304 / 316 stainless, aluminium, brass, copper and bronze with this stainless steel tube costed in 304 / 316 stainless steel.
The finish is chosen for the duty it will see: zinc and nickel plating, chrome, anodising, powder coating and passivation. It is written into the drawing for this stainless steel tube, so it cannot drift between batches.
The approved sample governs later runs, and grade changes have to be agreed in writing first.
Quality control
An ISO 9001 certified system governs production: incoming material is verified against mill certificates, the CMM measures the first article dimension by dimension, and every production run is inspected against the first-article report. First article of the part carries wall thickness data. Where the application asks for it, torque, leak or pressure testing is added to the plan, and the batch file carries the results.
Applications
The stainless steel tube is fitted into industrial equipment and general assembly work under schedules that run for years at a time.
The same stainless steel tube is often run in more than one assembly, so the finish is chosen to cover the harshest of them, without a second tooling round.
Customization and options
The options customers tune most
The parts of the print for this stainless steel tube that get adjusted: material and coating for the duty, wall bands, flange forms, threads and bosses, closed ends and finishes matched to the working environment, and how the order is released – sample, pilot run or scheduled call-off.
The quote for this stainless steel tube separates tooled options from new work, so there are no surprise tooling charges after approval. The part stays as approved until a written revision says otherwise.
Specifications
| Item | Capillary Tube Needle Tube 304 Stainless Steel Malaysia Bright Surface |
|---|---|
| Brand | AUNOV |
| Designing | Made to your 2D/3D drawings (PDF, DWG, STEP, IGS) – samples are reverse-measured into a controlled drawing; revisions are re-quoted once rather than silently absorbed. |
| Tooling | Die design and toolmaking stay in house, so no tooling step is outsourced, and the charge is refundable against agreed volumes. |
| Samples | Samples are issued for approval before the run, and production starts only after written sign-off. |
| Materials | Carbon steel (SPCC / DC01), 304 / 316 stainless, aluminium and brass are held on site; special grades are sourced to the drawing when volumes justify. |
| Surface finish | Plating, powder coating, anodising or polishing, per the print; masking and laser marking available where needed. |
| Processing | Drawn-tube process with in-line annealing and finish turning; batch records are filed so a repeat order starts from approved data. |
| Equipment | Drawn-tube benches, in-line annealing and CNC turning; secondary ops run on CNC turning centres, inspection on the CMM. |
| Tolerance | +/-0.03 mm on machined ends, straightness per print; dimensional reports accompany the first article. |
| Delivery terms | FOB, CIF or DDP per Incoterms 2020, payment by T/T, L/C at sight or D/P; price breaks tie to annual volume. |
Packaging and delivery
Packing for this stainless steel tube is chosen around the coating: interleaves, polybags or formed trays are selected according to the coating, then sealed cartons are palletised for export, with documents and marks to your instruction.
